I was following the directions in a previous thread about this problem here: http://forums.spiralknights.com/en/node/14480#comment-89252
After going through the process of re-downloading J2SE 5.0, going into my java preferences and moving the 64 bit to the top
The check box still does not show up at all.

It would be appreciated so much if someone could help me out with this.
